A study on Cormic Index among semi-urban Bengalee Boys of West Bengal, India.

Since stature is an additive measurement, it would be useful to examine the pattern of its constituent segments in terms of sitting height and subischial leg length for the evaluation and insight of various growth related issues as well. The aim of the present study was to understand the growth patterns with respect to height (HT), sitting height (SH), subischial leg length (SLL), Cormic Index (CRI) and their relationship with age. The present cross-sectional study includes 162 Bengalee boys aged 6-12 years. Age effect displayed significant positive correlation with HT (r = 0.734), SLL (r = 0.731) and SH (r = 0.637). However, CRI revealed significant negative correlation (r = -0.433) with age. This may be due to the fact that in these ages tempo of growth in SLL was higher than SH. Age-wise correlation between SH and SLL changes dramatically and varies from 0.474 to 0.750 due to the variation in the tempo of growth.
